CLEANING THE RELEASE VALVE
(BLEED THE PUMP)
Over time, the hydraulic pump assembly may
become clogged with debris, air bubbles, and
not function properly. To clean the release valve and
bleed the pump:
1. Pump handle quickly, raising pallet truck to max
height. While continuing pumping action, pull
lever to down position.
2. When forks reach total down position, valve is
flushed. Repeat if necessary.
LUBRICATION
Check the oil level annually by removing the oil plug
(Part #28 on the Pump Diagram) found on the top of the
pump housing. When changing or adding oil, fill the
tank through the oil plug screw hole to 80% capacity
with hydraulic jack oil, about 2" deep in pump housing.
(See Figure 3)
Please use Shell Tellus Oil: No. 22 or 27, Turbine Oil:
No. 22, or Texaco Regal: No. 32. Grease the rear and
front wheels annually or as needed.
Do not
use any other type of oil. There is one grease
fitting located on the table (Part #43 on the Pump
Diagram). Lubricate this point on a semi-annual basis or
as needed. Wheel bearings are sealed and require no
lubrication. Crank shaft features oil light bushings that also
require no lubrication. Lightly oil all other moving parts.
OPERATION
To raise the forks, place handle in the UP position
(bottom part of the handle slot). (See Figure 1)
To lower forks, pull lever handle to DOWN position
(upper part of the slot). (See Figure 1)
To freely move the handle, set the lever in NEUTRAL
position (center notch of slot). (See Figure 1)
TO LIFT A LOAD
1. Lower forks to lowest position.
2. Insert forks under load, or into pallet.
3. Place lever in UP position.
4. Move handle up, and down until forks reach
desired height.
TO MOVE A LOAD
1. Place lever in NEUTRAL position.
2. Pull or push pallet truck to desired location.
TO LOWER A LOAD
1. Pull lever to the DOWN position.
2. Pull forks away from load.
UP-DOWN CAM ADJUSTMENT
1. Set the lever in the NEUTRAL position.
2. Alternate turning the cam nut and pumping the
handle. (See Figure 2)
3. When lifting stops, give the nut one more turn.
4. The cam nut is properly adjusted when pumping
the handle in the NEUTRAL position causes no
movement of the hydraulic ram.
